Installing the battery
You have several battery options to power your
8IGHT starter box. You can use 7.2V Ni-Cd or
Ni-MH battery packs or a single 12V gel cell.
Pre-assembled wiring harnesses and mounting
fixtures for both of these options are included.
Please note the proper mounting and wiring
layout in Images 2 and 3. Start by moving the
chassis fixtures to the truggy (Long) position
as seen in Images 4 through 6 and explained in
the “Adjusting the Chassis Fixtures” section and
remove the small Phillips head screw on the top
of the box as shown in Image 1.
Two 7.2V battery packs
Install the holder and packs as seen in
Image 2. Plug one pack into each of the plugs.
Note: The plugs are keyed so they can
only be installed one way.

Gel Cell
Install the holder and gel cell as seen in Image 3
or the wiring diagram on Page 2. Note the Red (+)
and Black (-) terminals on the battery. Install the
jumper plug and battery power plug as shown.
Unless you plan on using the power terminals
next to the switch, you must tape and/or cut the
ends of the loose battery leads. Do not leave these
exposed as they can easily short out the battery
and cause damage and a safety hazard.
Adjusting the chassis fixtures:
For the 8IGHT buggy—rotate the front fixture
with the “v” pointing toward the end of the box
as shown in Image 4. Depress the lock button as
shown in Image 6.

Buggy Position
Move the rear fixture to the innermost
(short) position.
For the 8IGHT-T truggy—rotate the front fixture
with the “v” pointing inward as shown in image 5.
Depress the lock button as in image 6 and move
the rear fixture to the outermost (long) position as
seen in Image 5.
5
Starting
Place the chassis into the fixtures as shown in
Image 7. Note how buggy chassis sits in fixtures
and location of starter wheel.

Turn the power switch “ON” (Image 8).

Truggy Position
Press down on the rear of the chassis at which
point the motors should power up and the starter
wheel will engage the flywheel on the engine.
Note: If the engine is new, tight, or
flooded, it may be necessary to loosen
the glow plug 2–3 turns to get it
turning over. Re-tighten after engine
6
starts turning over. Do not continue
to stall the motors or allow the rubber
wheel to grind on the flywheel or
chassis.
After the engine starts, release the chassis—it
should be able to sit in the fixtures and idle
without interference. Turn switch off.

You can adjust the starter switch and the point
at which the motors start running by turning
the Phillips head adjustment screw (accessible
through the hole in the bottom of box as seen
in Image 9).
Tech/Service Tips
• On some models it may be necessary to relieve
the ends of the flywheel opening on the
bottom of your chassis (Image 10) to prevent
the chassis from interfering with the starter
wheel and allow the wheel easy access to
engage the flywheel on the engine.

Turning the adjustment screw counterclockwise
will allow the motors to start sooner and have
better starting power. Turning the adjustment
screw clockwise will start the motors later and give
you more travel before the motors start to power
up. You may want to adjust this to compensate for
starter wheel wear.
Ideally, the motors should start when the top plate
is depressed about 1/8-inch. If you find that the
motors are easily stalled while trying to start your
8IGHT, adjust the starter switch as noted above so
that the motors start sooner.
Troubleshooting Guide
Motors run slow
Battery(s) needs to be charged
Starter wheel won’t turn over engine
Loosen glow plug
Adjust switch to motors start sooner
Put a few drops of fuel in carburetor
Check for wheel interference with chassis
(See Image 10)
Check for starter wheel wear

mark the location of the mounting screws
before removing. Remove the screws on
either side of the wheel shaft. After replacing
the wheel, be sure to re-install the assembly
in its original position.
